The admiration for the BMW M3 has been amazingly high for many years as the M3 has been the leader in the class of high performance midsized luxury sedan models. There were times that other competitors tried to outclass the M3, there was the Audi B7 RS4 that took over for a short time and of course at Mercedes the AMG models can show up with some versions to take on the M3, but for years the M3 has been the leader and the class of only the midsized performance luxury sedans that show up as the best that is offered.
